Switch easily between measurement modes

The multimode function lets users switch between single-ended, differential and common mode measurements without reconnecting or resoldering the probe tip. The multimode function comes on the company-designed, high-speed R&S®RT-ZM amplifier ASIC.

Offset compensation for maximum resolution

The R&S®RT-ZM modular probe system has a unique offset compensation range of ±16 V. The DC components of a measured signal can be compensated at the probe tip, upstream from the differential R&S®RT-ZM amplifier ASIC. The operating voltage window can be extended beyond the dynamic range of the probe amplifier module and the signal components of interest displayed on the oscilloscope with maximum resolution. The feature is also available with multimode operation.

High precision DC voltage measurement

The integrated and unique R&S®ProbeMeter operates independently of the oscilloscope and measures DC signal components with 0.05 % accuracy. DC measurements are continuous and in parallel with the oscilloscope waveform acquisition. Immediate digitization of the measured DC voltage with a dedicated ADC inside the R&S®RT-ZM probe amplifier module enables the high precision.

Instrument control on the probe tip

The R&S®RT-ZM probe amplifier module comes with an integrated micro button that allows users to stay focused on measurement tasks and conveniently operate oscilloscopes. The micro button can be configured on Rohde & Schwarz oscilloscopes to perform a variety of functions, such as run/stop, auto set, save waveform, find trigger level, and create automated test report. Multimode switching can also be configured for the R&S®RT-ZM modular probe system.
